The InterPlanetary File System (IPFS) is a peer-to-peer, content-addressable, distributed file system that seeks to connect all computing devices with the same system of files. It is an open-source community-driven project, with reference implementations in Go and Javascript and a global community of millions of users.

IPFS resembles past and present efforts to build and deploy P2P and content-centric approaches to content storage, resolution, distribution and delivery. IPFS and libp2p — the modular network stack of IPFS — rely on name-resolution based routing. The content resolution system is based on the Kademlia DHT and content is addressed by flat hash-based names. IPFS sees significant real-world usage, with tens of companies building on top of its set of protocols, over 250,000 monthly active network nodes, millions of end-users, and wide adoption by several other projects in the Decentralised Web and beyond.

An adjacent project to IPFS is Filecoin. Filecoin is a token-based protocol that supports a decentralised storage and delivery network. Storage and retrieval miners are rewarded according to their contribution to the network and the mechanics of Filecoin secure the network against malicious activity.

The workshop will consist of a number of different sessions and session styles that go beyond a traditional presentations-only workshop and seek to foster interaction between participants. Hands-on sessions will give participants first-hand knowledge of how to use IPFS, while a capstone competition will give attendees the chance to develop open-source applications on top of IPFS and win prizes.

The workshop welcomes contributions in the following forms:

• Work-in-progress papers (limited to 6 pages).
• Abstract or position papers (limited to 2 pages).
• Demos (limited to 2 pages) showcasing a proof-of-concept prototype.
• Competition project ideas (limited to 1 page) to be included in the competition session, which will take place following the workshop.
